Yamaha have thrown an eye-catching new contender into the super-naked mix this year with the MT-10 – and now Yoshimura have provided owners with the chance of giving it even more pep.
The Alpha-T exhaust is an all-new design that’s been developed in conjunction with Suzuki’s MotoGP team and delivers a higher note than the company’s existing exhausts. It is also tapered in shape, which explains the letter T at the end of the name.
They’re made in Yoshimura’s factory in California from either stainless steel or titanium, both with a carbon-fibre end-cap. There are two finishes in stainless steel; polished for a mirror-like appearance, or Yoshi’s Works Finish, which is a satin finish that will be a better match for the stealth-like look of the MT-10.
The Alpha-T is available in either a slip-on silencer kit or a partial system, which means ditching the bike’s catalytic converter and pre-silencer collector box. That will free up extra power and save even more weight than by replacing the silencer alone.
Yoshi don’t quote exact power figures because much will depend on the original output of the bike before an exhaust is fitted. But they claim fitting their silencer should add around an extra 1.3bhp at the MT-10’s 11,500rpm peak and boosts torque by 1.3ftlbs. And expect a hike of around 3.8bhp at peak and 2.6ftlb by fitting the three-quarters system that acts as a de-cat.
Yoshi claim a weight saving of 300g by fitting the silencer and a 5kg drop with the stainless three-quarter, or a 5.6kg saving with the titanium version.
In terms of road-legality, the American-made Yoshimura exhausts aren’t tested to European emissions and noise regulations. But they pass the similar American tests and the UK importers say in terms of noise they will be almost identical to exhausts that do pass Euro rules.
Unlike most other manufacturers, who sell road-legal exhausts with removable baffles, Yoshi’s American exhausts come with the baffle included but not fitted so it’s up to the rider to fit it and reduce the noise levels.
In stainless steel the Alpha-T costs £517 for the silencer or £713 for the three-quarters system. Go for titanium instead and the prices increase to £742 and £1330 respectively.
